Is it true that the Missing Person File (QM) allows inquiries using non-unique identifiers?

The Missing Person File (QM) does indeed allow inquiries using non-unique identifiers, which include factors such as age and sex. This capability is critical because it enables law enforcement agencies and other relevant entities to broaden their search parameters when looking for missing individuals. Non-unique identifiers are valuable since many people might share the same name but differ in essential characteristics like age or gender, allowing investigators to filter potential matches more effectively.

This approach enhances the ability to locate missing persons by providing more context to the inquiries, which can be especially useful in cases where there is limited information available. The other options focus incorrectly on unique identifier requirements or limitations based on age or case type, which do not apply in the context of how the Missing Person File can be utilized.
